Introduction




What is digital electronics?




Digital electronics is a branch of electronics that deals with the representation, processing, transmission, and storage of information using binary digits (0 and 1). Unlike analog electronics, which uses continuous signals that vary in amplitude and frequency, digital electronics uses discrete signals that have only two possible values: on or off.


Digital electronics is based on the concept of logic gates, which are electronic circuits that perform basic logical operations such as AND, OR, NOT, NAND, NOR, XOR, etc. By combining these logic gates in various ways, we can create more complex circuits that can perform arithmetic, memory, control, communication, and other functions.


Why is digital electronics important?




Digital electronics is important because it is the foundation of modern technology. Almost every device we use today, such as computers, smartphones, tablets, cameras, TVs, etc., relies on digital electronics to function. Digital electronics enables us to process large amounts of data quickly and accurately, store and retrieve information easily and securely, communicate with others across distances and platforms, and create innovative solutions for various problems.


Digital electronics also has many applications in different fields such as engineering, science, medicine, education, entertainment, business, etc. For example:



  • In engineering, digital electronics is used to design and test electronic systems such as microprocessors, microcontrollers, embedded systems, robotics, etc.



  • In science, digital electronics is used to collect and analyze data from experiments and simulations such as particle physics, astronomy, chemistry, biology, etc.



  • In medicine, digital electronics is used to diagnose and treat diseases and injuries using devices such as MRI, CT, ultrasound, X-ray, pacemakers, etc.



  • In education, digital electronics is used to enhance learning and teaching using tools such as e-learning, interactive whiteboards, smart classrooms, etc.



  • In entertainment, digital electronics is used to create and enjoy media such as games, movies, music, etc.



  • In business, digital electronics is used to improve productivity and efficiency using systems such as e-commerce, online banking, digital marketing, etc.



Who is Salivahanan and what is his book about?




S. Salivahanan is a professor and the principal of SSN College of Engineering in Chennai, India. He has over 30 years of teaching and research experience in the field of electronics and communication engineering. He has authored several books and papers on various topics such as digital signal processing, electronic devices and circuits, linear integrated circuits, etc.


S. Arivazhagan is a professor and the head of the department of electronics and communication engineering at SSN College of Engineering. He has over 25 years of teaching and research experience in the field of electronics and communication engineering. He has co-authored several books and papers with Salivahanan on various topics such as digital signal processing, electronic devices and circuits, linear integrated circuits, etc.


The book by Salivahanan and Arivazhagan is titled "Digital Electronics: Principles, Devices and Applications". It was first published in 2007 by Tata McGraw-Hill Education. It is a comprehensive textbook that covers the fundamentals and advanced concepts of digital electronics. It is intended for undergraduate students of engineering and technology who are studying digital electronics as a core or elective subject. It can also be used by postgraduate students, teachers, researchers, and professionals who want to learn or refresh their knowledge of digital electronics.
